The Glasgow Hearing Aid Benefit Profile: What it measur es and how to use it... s-1there are lots of questionnaires around for assessing disability and hearing aid benefits. What was the motivation for generating this new one called the Glasgow Hearing Aid Benefit Profile (GHABP)? In the United Kingdom, the National Health Service provides hearing aids and associated rehabilitation free of charge to all clients. As in all healthcare systems, budgets are under pressure, and regimes of clinical governance and quality assur- ance are required. With the explosion of new technologic options in hearing aids, services and practitioners are required to demonstrate value for money, clinical effec- tiveness, and cost-effectiveness of services. 2So, how can the GHABP help? The GHABP aims to be a measure that can provide the appropriate system with information via psychometrically robust measures, and that also offers a degree of clinical utility to audiologic practitioners in managing individual patients. It is designed to distill the best features of various established approaches into one instru- ment, which is sufficiently short for application in clinical environments, yet gives usable and useful quantitative data. 3 You describe the GHABP s design for the United Kingdom National Health Service. How and why will it be applicable in other healthcare contexts, such as in North America? Although the particular context of the UK has driven the design of the GHABP, similar constraints and requirements apply to all forms of healthcare delivery. Funders of health care, be they individual clients, public systems, or insurance companies, require service providers to demonstrate the effectiveness and efficiency of their services. All audiologists wish to maximize the benefit that they deliver to their hearing- impaired clients and, therefore, it is suggested that the design principles behind the GHABP find a wider application than simply in the UK. 4 What are the various scales that the GHABP measures and why were they chosen? The GHABP can be regarded as a matrix whereby a variety of listening circumstances are polled to provide a number of different scales or dimensions encompassing disability, handicap, hearing aid use, hearing aid benefit, residual disability, and satisfaction. The questionnaire (see pages 16, 18) fits on a single sheet of paper, printed on both sides, with four pre-specified listening circumstances on one side and four further listening circumstances specified by the client on the reverse. The six scales or dimensions were chosen to provide the range of information required by system administrators, coupled with the information that audiologists require to make operational management decisions in the clinic. 5How do you intend to use the different dimensions from the GHABP? The first two scales initial disability and handicap refer to the client s perceived difficulties prior to intervention. Disability provides an indication of the types and degrees of difficulty that clients are experiencing, while handicap indicates the impact that those difficulties are having upon their everyday life. Pre-intervention scales of disability and handicap can guide the types of technical intervention and counsel- ing that can be clinically effective.

4 THE GLASGOW HEARING AID BENEFIT PROFILE: A CLIENT-CENTRED SCALE FOR THE ASSESSMENT OF AUDITORY DISABILITY, HANDICAP AND HEARING AID BENEFIT Stuart Gatehouse - MRC Institute of Hearing Research, Glasgow, Scotland BACKGROUND Outcome measures for the evaluation of adult hearing aid services find applications in programmes of quality assurance and act as tools for the assessment and tuning of management strategies within individual clients. It is argued that traditional disability and benefit measures that can be completed in clinically acceptable time frames can (i) ignore important components or dimensions of disability and benefit, (ii) rely on data not relevant to individual clients and (iii) result in insufficient discriminatory power for the targeting of management or the assessment of intervention. The Glasgow Hearing Aid Benefit Profile (GHABP) has been developed with the aim of maintaining clinical suitability and utility whilst providing outcome scales with sufficient statistical leverage to distinguish between alternative management regimes. This is achieved by accessing a number of different components of disability and benefit via a mixture of the perceived disability and benefit in both pre-specified and subject-specified listening circumstances of relevance to the hearing impaired client. COMPONENTS The GHABP consists of a single sheet of A4 paper printed on both sides. This firstly accesses four pre-specified listening circumstances which commonly occur in the lives of hearing-impaired clients. These are assessed separately as to (i) their occurrence, (ii) their degree of difficulty experienced by the listener (initial disability), (iii) the effect or impact on the hearing-impaired listener s life (handicap), (iv) the extent to which the hearing aid is used in that listening circumstance, (v) the extent to which hearing is improved in that listening circumstance (hearing aid benefit), (vi) the hearing difficulty experienced by the listener after the fitting of the hearing aid (residual disability) and (vii) the client s satisfaction with their hearing aid for that listening circumstance. The shaded portions of the GHABP identify the elements completed prior to management. The second page allows the listener to specify (up to four) additional listening circumstances of importance and relevance to their everyday communication circumstances. Only listening circumstances which exist in the listener s experience contribute to the scales of initial and residual disability, while only those which lead to a material disability contribute to handicap, use, benefit and satisfaction.
7 VALIDATION The validation of disability and benefit scales poses particular problems because of the absence of any gold standard. Therefore surrogates are required. These can take the form of statistical approaches such as item total correlation, test/retest variability, and aspects of construct and criterion validity, all of which are required and relevant. Here it is suggested that an external test of criterion validity can be applied across large numbers of subjects. After appropriate selection of and, control for, the initial impairment level, then a hearing aid prescription which improves audibility as measured for an ecologically-relevant signal (at a user-determined gain setting) by greater amounts will lead to greater benefits and reductions in disability and handicap than a hearing aid prescription which does so to a lesser extent. Thus, after a control for the appropriate variables, any outcome measure should be systematically related to the technical competence of the hearing aid fitting for that individual or group of hearing-impaired listeners. For this purpose, a validation criterion based on the improvement of the Speech Intelligibility Index (SII) for a speech spectrum at normal vocal effort is proposed. For reference, data from the hearing Handicap Inventory for the Elderly (HHIE) are included in addition to the hearing aid use, hearing aid benefit, satisfaction and derived benefit scales from the GHAPB. The results show the poor discriminatory power of the HHIE. The GHAPB retains the elements of clinical utility and relevance whilst exhibiting strong discriminatory abilities on the criterion index of improvement in audibility. Note that the psychometric properties of the direct benefit (or change) question exceed the index of derived benefit (computed from the difference between the two state scales of initial disability and residual disability).

17 SUMMARY This poster presents research to assess, develop, validate and calibrate a self-report measure of outcome suitable for the routine monitoring of service provision. A validity criterion is proposed. Outcome measures to assess the benefits of intervention should be systematically related to the technical competence of the intervention. The multi-dimension subject-specific and situation-specific scales from the Glasgow Hearing Aid Benefit Profile pass the criterion and demonstrate significant discriminatory power. The subject-specific communication circumstances contribute to discriminatory capability. A direct change question is more sensitive than the difference between two state scales. The Glasgow Hearing Aid Benefit Profile furnishes scales covering initial disability, handicap, hearing aid use, benefit, satisfaction and residual disability. The data enable the evaluation of the extent to which proportions of the hearing-aid users have their levels of auditory disability reduced to various criterion values of percentiles in the control populations. Inspection of the scales of reported use, benefit and satisfaction allow the magnitude of the increases attributed to pre-fitting counselling to be evaluated in the light of resource requirements. The scale properties of the outcome measures derived in this research have allowed clinics and policy officials in Scotland to interpret the increased benefits delivered by modular ITE technology in the light of the service implications. It is argued that the GHABP may be implemented as part of a quality assurance programme while making a substantive contribution to individual patient management.

27 EXAMPLE OF COMPLETION AND SCORING OF THE GLASGOW HEARING AID BENEFIT PROFILE The first situation - Listening to the television with other family and friends when the volume is adjusted to suit other people is reported as occurring in the life of the listener, causing great difficulty, a moderate amount of handicap, hearing aid is used around three-quarters of the time, hearing aid is quite helpful, following management having only slight residual disability and leading to reasonable satisfaction. The second listening situation - Having a conversation with one other person when there is no background noise is reported as occurring, but leading to no difficulty. The subsequent five columns are then set as Not applicable. The third listening situation - Carrying on a conversation in a busy street or shop is reported as not occurring in the listener s lifestyle. Therefore, all seven of the subsequent columns are set to Not applicable. In the fourth pre-specified listening circumstance - Having a conversation with several people in a group, the situation is reported as occurring, leading to moderate difficulty, quite a lot of handicap, hearing aid used around a quarter of the time, with hearing aid benefit being some help, leading to moderate residual disability, and a little satisfaction. This particular listener (please note that all of the data here are quite arbitrary) then takes the opportunity of specifying three further listening circumstances which are a) listening to music, b) attending business meetings, and c) attending social gatherings. The data are as entered on the second (usually the second side, but here second sheet) of the GHABP. Turning then to the scoring. For the first column, representing initial disability, there are six listening circumstances which contain applicable data with scores of 4, 1, This is the end of the SAMPLE GHABP-KIT validity & scoring instructions.
